| EPA chemical substance information | information provided by: ofmpeb.epa.gov (external link) |
| Introduction | Paraffinic Oil (or Paraffinic Oil) refers to, in particular, any of the colorless, odorless, higher alkanes extracted from petroleum fractions. Generally, paraffin oil is a by-product in the process of manufacturing gasoline by fractionating petroleum and petroleum raw materials. Paraffin oil is transparent, colorless, mainly composed of alkanes, cyclic paraffin (related to Vaseline). Paraffin oil can be divided into light, heavy grade, its density is about 0.8g/cm3. Paraffin oil production is very large, the price is low, often sold in pharmacies. |
